You build monuments to your success. Resist the urge to construct fancy new headquarters, a clear sign of the company’s sense of victory. “It can also lock a company into a community—a double-edged sword,” Sull writes.

You name monuments after your success. Renaming football stadiums, ice hockey rinks, and the like “is another red flag that sometimes signals success has gone to managers’ heads.” (“주가를 위해서는 본사 빌딩과 CEO의 집은 평범해야” 참조)

Your CEO writes a book. The success formula becomes public and is harder to amend later.

Your top executives look alike. Look around. Your company won’t stretch itself when all the managers think alike and see the business in the same way.

Your competitors all have the same zip code you do. “In some cases, not just one company but an entire community of firms latches onto the same success formula” as happened with Akron, Ohio with tires; Detroit, Michigan with automobiles; Sheffield, England with steel; and Jura, Switzerland with watches.
